contamination to enter the hydraulic system.

4.

Remove and retain the oil-fill port fitting, and
position the transmission so that the oil drains
completely out of the housing.

5.

When all the oil has drained from the transaxle,
remove and retain the #10-32 x 1/2 inch
self-tapping screw and the ratchet fastener
holding the expansion tank to the housing.

hose into the tank. Place the tank opening over
the O-ring, and push down to ensure a proper
seal. Install the #10–32 x 1/2 inch self-tapping
screw, and torque it to 25 in-lb (2.8 N
